The synthesis, characterization and diuretic activity of four new biologically active complexes of Mg(II) and VO(II) with bidentate Schiff base ligand acetazolamide-salicylaldimine (L) obtained from the inserted condensation of 5-acetamido-1,3,4-thiadiazole-2-sulphonamide (acetazolamide) with salicylaldehyde in a 1:1 molar ratio have been reported. Using this bidentate ligand complexes of Mg(II), Mn(II), Fe(II) and VO(II) with general formula ML 2 have been synthesized. The synthesized complexes were characterized by several techniques using elemental analysis, FT-IR, electronic spectra, TGA, mass, particle size analysis and molar conductance measurements. The elemental analysis data suggest the stoichiometry to be 1:2 [M:L]. The molar conductance measurements suggest non-electrolytic nature of the complexes. Infrared spectral data agreed with the coordination to the central metal ion through deprotonated phenolic oxygen and azomethine nitrogen atoms. On the basis of spectral studies, octahedral geometry is suggested for Mg(II), Mn(II), Fe(II) and square pyramidal geometry is suggested for VO(II) complexes. The pure drug, synthesized ligand and metal(II) complexes were screened for their antimicrobial activities against Eschericia coli, Bacillus subtilis, Aspergillus niger and Aspergillus flavous. The results show that the metal complexes were more active than the ligand and pure drug against these microbial species as expected. The ligand and its Mg(II) complexes was screened for their diuretic activity also. © 2011. Source

The probability of incomplete fusion in 13C+159Tb interactions has been measured in the energy range ≈4-7 MeV/nucleon. The variation of the incomplete fusion fraction has been studied in terms of projectile energy and type. Present results are compared with the existing 12C+159Tb data, where a strong projectile structure effect on the incomplete fusion fraction has been observed. It has been found that the probability of incomplete fusion is higher in the case of 12C than for a one-neutron rich 13C projectile. For better insight into the projectile structure effect, a systematic study is presented on the incomplete fusion measured in 12 ,13C,16O+159Tb and 12 ,13C,16O+181Ta systems by Singh and by Babu. The present analysis indicates a strong dependence of incomplete fusion probability on the α-Q value of the projectile at these low energies. © 2012 American Physical Society. Source

The presented work deals with the synthesis and thermal characterization of TiO2 filled Polycarbonate/Polystyrene (PC/PS) blend nanocomposites. Nanoparticles of Titanium-dioxide have been synthesized by simple chemical method. Average grain size of as prepared nanoparticles have been determined by both TEM and XRD. Titanium-dioxide Filled Polycarbonate/Polystyrene blend nanocomposites have been prepared by solution casting method. The XRD pattern and FTIR spectrum confirm the formation of blend nanocomposites. Differential Scanning Calorimetry (DSC) has been used to study thermal properties. The DSC thermograms indicate that the glass transition temperature and hence thermal stability of nanocomposites enhances with addition of filler content. © 2015 WILEY-VCH Verlag GmbH & Co.

New adducts of thiotrithiazyl chloride with hydrazine and phenyl hydrazine have been synthesized and characterized on the basis of elemental, mass electronic, IR, NMR and ESR spectral studies. The adducts was screened against the gram-ve bacteria, E.coli and S. typhimurium and fungi, C. albicans and C. neoformans. The both hydrazine and phenyl hydrazine adducts are found to be active against the fungi C. albicans and the bacteria E. coli and S. typhi except C. neoformans. Source

This paper describes the combined wall slip and reliable MHD steady flow of the conducting viscous incompressible fluid through channels permeable boundaries. The governing equations have been solved by Finite Difference Technique. The analytical results and conclusions have been presented and discussed through various graphs. Results presented in this paper revealed that the fluid velocity can be replaced by a magnetic field and the wall slip. Appropriate result shows that the wall skin friction increases with suction and decreases with injection. Copyright © 2010 Inderscience Enterprises Ltd. Source
